The angular resolution of large telescopes are limited by turbulence in the earth’s atmosphere. This limitation can be dramatically reduced with the use of Adaptive Optics (AO) to measure and correct the blurring introduced by the atmosphere. AO is becoming routinely used for science observations on the world’s modern observatories, and is providing much better observations of the universe.

The SOAR Adaptive Module (SAM) is a laser-assisted adaptive optics system at the 4.1-m SOAR telescope. By compensating selectively low-altitude turbulence sensed by a UV laser guide-star, it improves resolution at visible and near infrared wavelengths. SAM covers a 3-arcmin square field and can feed light to small visitor instruments attached to its port.

About Andrei Tokovinin:

Dr. A. Tokovinin got his first (PhD) degree in 1980 at the Moscow University. Since then, he worked with astronomy at multiple locations, such as, Sternberg Astronomical Institute (Moscow University, Russia), Mount Stromlo Observatory (Australia), Nice University, Grenoble and Lyon Observatories (France), and European Southern Observatory (Germany). Since 2001, he works as an Associate Astronomer at the Cerro Tololo Inter-American Observatory in Chile. 

Tokovinin's main scientific interests include multiple stars, astronomical instrumentation, interferometry, radial velocities, atmospheric optics and site testing. His practical experience includes computation of the orbits of binary stars, processing of adaptive optics and corongraphic images (in IRAF or MIDAS environment), building a fiber-fed echelle CCD spectrometer and some other instruments, as the SAM (SOAR Adaptive Module).

About 90 papers have been published in the refereed journals in the period 1974-2000, plus several reports in the conference proceedings and two books: ``Stellar Interferometers'' (1986, in Russian) and ``New imaging methods in astronomy'' (1990, a review).
